⁸²Rb and [¹⁵O]H₂O myocardial perfusion PET imaging: a prospective head to head comparison.

ABSTRACT:

Background

⁸²Rb PET and [¹⁵O]H₂O PET are both validated tracers for myocardical perfusion imaging but have not previously been compared clinically. During our site's transition from ⁸²Rb to [¹⁵O]H₂O PET, we performed a head-to-head comparison in a mixed population with suspected ischemic heart disease.

Methods

A total of 37 patients referred for perfusion imaging due to suspicion of coronary stenosis were examined with both ⁸²Rb and [¹⁵O]H₂O PET on the same day in rest and during adenosine-induced stress. The exams were rated by two blinded readers as normal, regional ischemia, globally reduced myocardial perfusion, or myocardial scarring. For [¹⁵O]H₂O PET
